Changing Job with EAD

[indianinhouston]

Hi

Have been with my present company in US for 7 years.

They -

Sponsored filing of PERM II under EB2 and I140 - obtained in 2009
I485 - obtained in March 2012 for self, wife and child. Followed by EAD.
EAD - renewed in March 2013. Expenses borne by present company.
Currently working on EAD which is due for renewal in March 2015.

Now I am planning a job change in US and my present company says that they will cancel the sponsorship and I140. What does this mean?
Does it mean cancellation of I485 as well? I have always thought that one can change jobs on EAD(similar type of job) and file AC21 during the change.

Please advice

Your understanding is correct. You can use AC21 and work for another employer in the "same or similar" position without the need to refile. Cheers!
